I requested stop signs coming on/off this bridge. Drivers FLY over this bridge. Why can't we get some attention to this very serious issue?????? I pickup my Grandaughter every day of the week and I take a left at the end of Saltonstall and on my return, I take a right onto bridge once again. Let me tell you two times I was nearly in a major accident! Because drivers fly on this bridge. WE NEED SOMETHING DONE ....... BEFORE WE HAVE A MAJOR ACCIDENT OR WORSE, please make this top of your list, PLEASE. I do not want to be a victim. Thank you!!!

I will echo Ms Powers comments. People fly down grove st and even the “speed bump” further down is not a deterrent. Once they see the new road coming around the corner from the cemetery, they fly almost to route 60. Coming from 60, it is a speedway with no regard for the speed limit.
There are new young families in the area and I only hope it doesn’t take an accident and injury to get some attention.

I'm glad the new pavement does not have a stripe down the middle (studies have shown that a painted centerline encourages speeding, like https://usa.streetsblog.org/2014/08/15/removing-center-lines-reduced-speeding-on-london-streets/) (they speed because they feel protected from head-on crashes...but of course are now at greater risk of clipping somebody entering/leaving a side street)

The speed table near Newton Rd / Jackson Rd seems to have helped some, particularly reminding Northbound drivers before they come onto this section of Grove...but they seem to "forget" by the time they get to Saltonstall.

Southbound, I think the problem starts on Grove all the way back at the Brooks Estate, where the road is very wide open, and seems to encourage people to speed up in the blocks before the bridge. If there were some way to make the road feel slower and narrower on the North side of the bridge, it probably would help on the south side.

Also, the "Blind Driveway" sign (at the corner of Grove & Saltonstall) comes way too late: by the time someone going 30mph has read and processed it, the'd've already turned onto Saltonstall and had their accident.

The current pole opposite 156 Grove Street would be a good place for a sign warning northbound of closely spaced T-streets the left (Laird Rd and Saltonstall)
specifically an MUTCD W2-8L (photo included)

Southbound on Grove as one approaches the Bridge, we should also be warning people that Saltonstall and Laird are coming up immediately on the other side of the bridge.

Currently, the bridge does have a sideways T (an MUTCD W2-2 that technically warns of Saltonstall) but given that Laird is so close after, it seems that an MUTCD W2-8R would be better (pictured)
